Compare models
Put models side by side on price, context, capabilities, and benchmarks.
o1-pro is a higher-compute version of OpenAI's o1 reasoning model for the hardest math, science, and coding problems. This is the batch variant for cheaper asynchronous processing.
Claude Haiku 4.5 is Anthropic's fast, affordable small model in the Claude 4 generation, balancing strong instruction-following and coding ability with low latency. It is designed for high-throughput agentic and chat applications where speed and cost efficiency are priorities.
